Pipe Weight Calculator
Calculate steel pipe weight per metre, per foot and per length. Enter the outside diameter and wall thickness in mm or inches; it works for MS, GI and stainless pipe and tube.
Theoretical weight from nominal sizes. Actual weight varies with mill tolerance and, for rolled angles, channels and beams, the corner radius. Steel price in the UAE today: see the current price per ton.
Steel pipe weight formula
Weight (kg/m) = (OD − wall) × wall × 0.02466, with OD (outside diameter) and wall thickness in mm. In imperial units, weight (lb/ft) = 10.69 × (OD − wall) × wall, in inches.
Example: a 2 inch SCH 40 pipe is 60.3 mm OD × 3.91 mm wall, so it weighs (60.3 − 3.91) × 3.91 × 0.02466 = 5.44 kg/m, or 32.6 kg per 6 m length. In imperial units it is 3.66 lb/ft.

MS, GI and stainless pipe
MS (black) and GI (galvanized) pipe use the same steel density, 7.85 g/cm³; hot-dip galvanizing adds a little zinc, usually a few percent of the weight. For stainless pipe choose grade 304 or 316 in the calculator; it is about 1 to 2% heavier than carbon steel for the same size. For square and rectangular hollow sections, choose Square / rectangular tube.

Frequently asked questions
How do I calculate MS pipe weight per metre?
Use (OD − wall) × wall × 0.02466 with sizes in mm. A 2 inch SCH 40 pipe (60.3 × 3.91 mm) weighs 5.44 kg/m.
What is the pipe weight formula in lb/ft?
lb/ft = 10.69 × (OD − wall) × wall, with OD and wall thickness in inches.
How much does a 6 m length of 1 inch SCH 40 pipe weigh?
About 15.0 kg: 33.4 mm OD × 3.38 mm wall is 2.50 kg/m.
Is GI pipe heavier than MS pipe?
Slightly. The steel is the same, and hot-dip galvanizing adds a zinc coating that usually adds a few percent to the weight.
What does SCH 40 mean?
Schedule 40 is a wall-thickness series for pipe. For the same nominal size, SCH 80 has a thicker wall and weighs more.
